Installation Worksheet For Projecting On A Pre-Installed Wall-Mounted Board - Epson BrightLink 475Wi Installation Manual

Installation worksheet for projecting on a pre-installed wall-mounted
board
1. Measure the ceiling height (distance from the floor to the ceiling).
2. Measure the height of the board's image area (h).
3. Measure the width of the board's image area (w).
4. Measure the distance from the floor to the bottom of the board's image area (f ).
5. Measure the distance from the ceiling to the top of the board's image area (d).
6. Measure the thickness of the board (distance from the projection surface to the wall) (x).
10 in. (254 mm)—height of
wall plate plus cover
Required distance from top
of image area to bottom
holes of wall plate (c)
Height of
image area (h)
0.8 in. (20 mm)—
distance from bottom
of image area to
bottom of board
7. Determine the aspect ratio of the board or of the images that will be projected. For
new computers or laptops, this will most likely be WXGA (16:10). For older equipment,
this will most likely be XGA (4:3). You may need to consult your IT department for this
information.
___ 4:3 XGA
8. Using the tables on pages 21 to 28 for your aspect ratio and desired image height (h),
find the required distance between the top of the image area and the bottom holes of
the wall plate (c).
9. Determine the position for your projector installation by adding the values for (f), (h),
and (c), plus an additional 10 inches for the height of the wall plate plus the cover.
If the ceiling height of your room (as noted in step 1) does not meet the minimum
ceiling height required for your board, you may need to select a smaller image size or
move the board to a lower position on the wall.
10. After confirming your image size, use tape or a pencil to mark the distance (c) from the
top of the image area on the board to the bottom holes of the wall plate.
11. Align the line (horizontal) on the template sheet with the (c) mark, then align the
center line on the template sheet with the center of the image area. Follow the
instructions on page 30 to install the projector.
